Seat
Nathaniel and I are a little overexcited about getting inside the airplane so we can finally make airplane noises. I keep reminding him we have to put the seat in first. Looks like we are getting closer to that goal.
I had already drawn all the cut lines and bend lines on the seat, so I double-checked them, cut the holes and bent it on my homemade sheet metal brake.
Got a little help polishing
While I had the bottom of the forward fuselage removed, I decided to polish it. Since only insane perfectionists will ever see it closer than 200 feet away (while laying down on the hot ramp under the plane), this might be the only polish job it ever gets. I heard that corn starch helps with removing the black residue, so Nathaniel and I gave it a try. Works pretty good.
Nathaniel’s paper towel is still pretty white, but he was trying pretty hard.
It seems like he found a loose bolt, but I’m pretty sure there aren’t supposed to be any bolts right there. With the two of us working on this now, we should get the plane finished in no time.
Riveting fuselage former
Archie came over again and helped me rivet the last two fuselage formers in place.
This week I completely disassembled the forward fuselage, deburred them, and added a hole for the rear spar on the left side. I then reattached the sides, bolted, and riveted the skins. I started riveting the spar tunnel in place with flush rivets.

Dad helped with the forward fuselage
Dad helped me align the aluminum channel on the floor of the fuselage. The two center aluminum channels were too close together and sandwitched between two aluminum angle extrusions. This prevented us from being able to use the pilot holes in the channel as guides to drill into the extrusions. This situation seems to be a “feature” of the lowered seat modification. It would have worked great had I not already riveted the extrusions in place. I ended up drilling one out to get access. This was awkward and I ended up breaking a drill bit in the process.
Seat mount, etc.
I’ve been spending a lot more time under the fuselage drilling into the spar tunnel, seat support, forward fuselage/rear fuselage skin overlap, etc.
Here are a bunch of the parts I have been working on set in place. The part with the clamp and the piano hinge is where the bottom of the seat attaches. I have begun to pilot-drill that and cleco it into position.
I haven’t taken a picture of it yet, but I also built the elevator push-rod idler.
Attaching forward fuselage sides
Started attaching the forward fuselage sides. I got an Park Tool TW1 torque wrench to help with some of the bolts. This is a lot easier to use and smaller than my clicker-style wrench and great for these bolts. I used fishing line (notice the fishing reel hanging off the front left longeron) to check that the longerons are straight and a laser line to double-check. I believe the next step is to attach the bottom to help further line everything up, but I believe it is pretty close as it rests now.
